Question

I have a jar compiled with core jdk.

It contains a java class which reads a txt file.
It has a test which proves that this class works correctly.

If I include this jar in my android project and then call the java class that reads the txt file. It fails reporting: java.io.FileNotFoundException and adding a ‘/’ to the path of the txt file which I wanted to load.

Is Android’s security model stopping the txt file from being read?

My Project structure:

Android Module:

src/Loader.java [calls GetName.java]

Java Module:

test/TestGetName.java [calls GetName.java]

src/GetName.java

resources/names.txt

Summary:

TestGetName.java works

Loader.java fails. A FileNotFoundException is thrown inside GetName

Answer 1

Figured it out in the end. I need a condition to see if I am loading the file locally or as a resource. There is probably a neater way to do this without using a conditional.

    String source = "resources/inputfile.txt";
    BufferedReader fin;

    InputStream inputStream = getClass().getResourceAsStream(source.substring(source.lastIndexOf("/")));
    if (inputStream != null) {
        fin = new BufferedReader(new InputStreamReader(inputStream));
    } else {
        fin = new BufferedReader(new FileReader(new File(source)));
    }

Thanks for the hints about reading as a resource user77777777
